Titanium dioxide (TiO2)
scientific name titanium dioxide, is a white powder, slightly yellowish when heated, and is a white pigment whose main component is titanium dioxide (TiO2). Its molecular formula is TiO2, which is a polycrystalline compound. Its particles are regularly arranged and have a lattice structure. . Titanium dioxide has the smallest relative density. In the entire titanium industry, rutile and ilmenite consumed in the production of titanium dioxide account for 90% of the total consumption, and only 10% of the titanium-containing materials consumed in the production of metallic titanium (sponge titanium).
Titanium dioxide (titanium dioxide) is chemically stable and does not react with most substances under normal circumstances. Titanium dioxide has three kinds of crystals in nature: plate titanium type, anatase type and rutile type. The plate titanium type is an unstable crystal type and has no industrial value. Anatase type is referred to as A type and Rutile type is referred to as R type. Both have stable crystal lattices and are important white pigments and porcelain glazes. Compared with other white pigments, it has excellent whiteness, tinting power, hiding power, weather resistance, heat resistance, and chemical stability, especially non-toxic.
Used in Coating Industry:
The coating industry is the largest user of titanium dioxide, especially rutile titanium dioxide, which is mostly consumed by the coating industry. Coatings made of titanium dioxide are bright in color, high in hiding power, strong in tinting power, low in consumption, and many in variety. They can protect the stability of the medium, and can enhance the mechanical strength and adhesion of the paint film and prevent cracks. Prevent UV and moisture from penetrating and extend the life of the paint film.
